Abstract EN
The present study considers an influence of WS2 nanoparticles lubricants on physical characteristics of wrought Aluminium alloys.
It is investigated parameters-performance relationship via tribological pin-on-disc tests, the pin is made of Aluminium alloys and the disk is made of AISI.1045, and the humidity was 70%.
Oils with WS2 nanoparticles and without them reveal the loss rate of wear.
In this study, the coefficient of friction (CoF) is reduced from 0.27 to 0.22 and the wear rate decreased from 0.128 x 10-6 Nm-1 to 0.107 x 10-6 Nm-1 at a load of 20 N.
All worn surfaces were typically three types in wear mechanisms such as adhesive, abrasive, and oxidative wear.
In addition, the use of nanoparticle enhanced the viscosity.
This study showed promising results and concluded that the wrought Aluminium alloy to be the superior with WS2 nanoparticles, Furthermore, the wear rate has been reduced of 14% comparison without the use of WS2.
